APPARATUS FOR IMPREGNATINQ' LIQUTDS WITH CARBONIC ACID.

To all whom it may concern: Y Be it known that I, ANDERs ANDERSENPINDSTOFTE, manufacturer, subject' of the Kingdom of Denmark, residingat No. 62 F rederiksberg Alle, in the city of CopenhagenfDenmarhZ-ha-veinvented new and useful Improvements in Apparatus for ImpregnatingLiquids with Carbonic Acid, of which the following is a specification Myinvention relates to an improved apparatus for, impregnating liquidswith carbonic acid and it consists iIl-tllGQCOIlSUllC: tions,combinations and arrangements herein described and claimed.

My invention provides an improved apparatus by"which an excess ofcarbonic acid is passed upwardly through a compact ascending column ofliquid, for thoroughly expelling and removing the air from the latter inorder to permit the liquid to be fully saturated with carbonic acid;

My improved apparatus enables liquids to be fully saturated withcarbonic acid at comparatively high temperatures, and elnninates theexpense of cooling the liquids before treatment. Further, I amenabled tofully saturate liquids with carbonic acid at relatively low pressures,thereby avoiding danger of troublesome and expensive bottle breakage andloss. I

The accompanying drawing, forming a part'of this application,illustrates one embodimentof my invention in which a narrowandrelatively high impregnating chamher a is provided with a supplypipe 6for the liquid under treatment; said supply pipe extending from the topof the chamber a to near its bottom. A supply pipe c'for carbonicacidprovidedwith a valve leads into the chamber a little above the lowerend of the pipe 6. The chamber a is provided with perforated partitionsd arranged at suitable distances apart. The upper part fot'theimpregnating chamber a is enlarged and pro" vided with a bottlingpipe 9 and an air outlet pipe 71 As illustrated the ipe Z) may beprovided with a valve 1' contro led by a float c', which valve when thelevelofthe liquid 1 rises to a certain height automatically cuts oil"the supply of liquid to the impregnating chamber.

Above the apparatus is arranged a liquid reservoir or a number (forexample t ree) *oi sjichreservoirs A, B aid 0, the lower parts of whichare connected through pipes l, 2 and 3, provided with valves to pipeSpecification of Letters Patent. p t t d June in, 1913, Applicationfiled October 14, 1911; Serial No. 654,756.

0, which inturn is connected to the liquid supply pipe b, so that,ifmore than a single reservoir is provided, the impregnatingv chamber acan alternately be supplied from one or another of 'said reservoirs. Thereservoirs A, B and C are connected to each otherby a pipe p providedwith a valve for each of thereservoirs. Y

Liquids are supplied to the reservoirs through apipe 8 (provided with avalve for each of the reservoirs) connected to a pump or a reservoir forwater under pressure. The air outletpipe h ofthe apparatus is connectedto a pipe r, which through branches 4:, 5 and 6, provided-with valves,is connected to the upper part ofthe reservoirs, A, B and C, so that thequantity of carbonic acid necessary for the filling of the space in saidreservoirs from which the liquid is taken can be supplied to thereservoirs, through said pipes but only afterhav- 'ng passed throughthe. liquid in the impregnating chamber a. I

The operation of the apparatus is as follows The liquid is suppliedthrough the pipe b and rises through the impregnating chamber a togetherwith the carbonic acid supplied through the pipe '0. During its passagethrough the. small holes in the partitions d the carbonic acid becomesthoroughly mixed with the liquid by which it is absorbed in the highestpossible degree expelli'ngthe air contained in the liquid- The liquid issupp lied alternately to the impregnating chamber from one or anotherof'the reservoirs A, B and C. -The liquid impregnated in the chamber ais bottled through the pipe 9, while the air expelled from the liquid bythe excess of carbonic acid is conducted through the pipes h and r tothe space above theliquidin the reservoir in action the quantity ofcarbonic acid necessary for the filling of the space left by the liquidin said reservoir isthus caused to pass through the impregnating chamberand the liquid supplied to it, during which passage the manifold smallerspecificgravity of the carbonic acidrelatively to the liquid will causethe carbonic acid'to risethrough the liquid with an excessively greatspeed, thereby putting the liquid in a violent whirling motionduringwhich the air contained in the liquid is released and carried awaywith the carbonic acid. l claimz v in an apparatus for impregnatingliquids closed impregnating chamber, a number of partitions providedwith small holes and arranged above one another in said impregnatingchamber, a supply pipe for carbonic acid inserted near the bottom ,ofsaid chamber, and an air outlet pipe leading from the top of saidchamber, with a supplypipe for the liquid to be impregnated, which"supply pipe extends fromthe top of the chamber. to near its bottom, abottling pipe lead ing from the top of the chamber, and a'liquid'reservoir arranged above said chamn'ected to the liquid supplypipe; substan-' tially as-described and illustrated and for the purposespecified' In testimony whereof I h'avesigned my "name to thisspecification in the presence of 20 two subscribing witnesses.
